a glass flask of volume 400 cm cube is just filled with Mercury at zero degree Celsius how much marks are you will overflowing the temperature of system Rises up to 80 degrees celsius

5.76 cm³

Explanation:

Using the equation for volume expansivity,

V = V₀ + V₀γΔθ) where V₀ = volume of cube = volume of mercury = 400 cm³, γ = cubic expansivity of mercury = 18 × 10⁻⁵ /K and Δθ temperature change = θ₂ - θ₁ where θ₁ = 0 °C and θ₂ = 80°C. So, Δθ = 80°C - 0°C = 80°C = 80 K

Now, the volume change, ΔV = V - V₀ = V₀γΔθ.

So, substituting the values of the variables into the equation, we have

ΔV = V₀γΔθ

= 400 cm³ × 18 × 10⁻⁵ /K × 80 K

= 5.76 cm³

So the mercury will overflow by 5.76 cm³.

the answer is 46 mls because when you add the speed per second it increses the speed
